Abstract

We review the principle of operation of several reflective fiber optic interferometers and combinations of interferometers that produce an output signal proportional to the derivative, or the product of the position and the derivative of an external phase perturbing signal. The unbalanced Mach-Zehnder or modified Sagnac interferometer, the reflective-ring and the differentiating-ring interferometers, and two other sets of interferometer combinations are discussed. The use of these interferometers is illustrated as sensors for the waveforms of multi-phase alternating currents, an as impact or disturbance position sensors.
